问题描述
我对Spring框架有疑问，我一直在寻找解决方案，但是没有结果.
I have problem with Spring framework, I was searching for solution long time, but any result.
部署应用程序时，出现异常:
When I Deploying an application, I get Exception:

问题解决了.我必须将beans.xml包含在xx-servlet.xml配置中.
problem solved. I had to include beans.xml into xx-servlet.xml config.
推荐答案
setter注入未正确应用.在春季，您无法致电新接线员.研究setter和构造函数注入.这是setter注入的示例...请尝试以下方法:
The setter injection is not applied properly. In spring you cannot call the new operator. look into setter and constructor injection. Here is an example of setter injection...Try this:
@Repository
public class UserDaoImpl implements UserDao {
@Autowired
private JdbcTemplate template;
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
@Override
public List<User> findAll(){
return this.template.query(Sql.SQL_QUERY_FIND_ALL ,new UserRowMapper<User>());
}
@Override
public User fintById(long id){
return this.template.queryForObject(Sql.SQL_QUERY_FIND_BY_ID, new Object[]{id}, new UserRowMapper<User>());
}
@Override
public void create(final User user){
...
}
@Override
public void delete(User user){
this.template.update(Sql.SQL_QUERY_DELETE, new Object[]{ user.getId() });
}
DBContext:
<jdbc:embedded-database id="dataSource" type="DERBY">
<jdbc:script location="classpath:create-schema.sql"/>
</jdbc:embedded-database>
<!--JDBC Template Bean...-->
<bean id="reportJdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource" />
</bean>
对于存储库/DAO类，请使用@ 存储库注释，而不要使用@Component.确保为DAO类启用了基础扫描，以便Spring可以找到并注入它们.您不必使用@ Service，@ Repository和@Controller注释来显式定义要注入xml文件的bean.
For repository/DAO classes use @Respository annotation, rather than @Component. Ensure that the base scan is enabled for the DAO classes so Spring can find and inject them. You don't have to explicit define the bean to be injected in the xml file with @Service, @Repository and @Controller annotations.
<context:component-scan base-package="com.something.dao"/>
希望有帮助.
